.l'o all whom it mag concern: L Be'it known that}, EDWIN Ann. EMERY, a

citizen of the United States, and a resident of: j Cripple Creek, in the county of Teller and v5- State of Colorado, have invented new and useful :Im rovements in Lubricators for Pneumatic Iachinery, of which the following is a full, clear, and exact des'criptidn. "My'invention relates to improvements in lubrlc'atoi's es ecially designed for use in machinery oi, iflerent kinds depending upon' compressed air as the motive oWer--suc'h, for'exam le,'as air-drills, coa -cutters, air- ---hoists, and mining 'rnachinery+although I do rsinot desire to strictly confine myself to the described application of the lubricator to a parv "-ticular-class of machinery. p v

vI'njthe present invention I em loy a construction adapted togcontaina cartrid e Zen: charge of solidified oil or grease treate to,

' f'make it soluble when attacked by moisture,

I wand around or adjacent to this cartridge the motive fluid is caused to circulate, so thatthe .-,cartridge is caused to dissolve by its afiinitv for the moisture contained in the motive fluid,

\ tre'nt oi the' motive fluid and carrie into the machine, or the parts it is desired "to lubricate.

It is well known that pneumatic machinery requires lubrication in proportion to the mois'turejin the air, and the resent invention ,iSdBSiQIlGd to .automatical y meet these re quii'ement's. The lubricator is so'construct- .edthat its method of'use on mining arid other gyprneumatic machinery renders it peculiarly ee fromaccidental damage resulting from rough or careless handling. The action of the dissolved compound is cleaning in effect I .;and thoroughly overcomes the accumulation 40 of grit, thus increasin the serviceability of the apparatus and ma 'ng it, 'to a great extentfmdependent of the care of the operator. Whenused in connectionwith a throttle or. pluggcock, the device supplies the lubricant to t .45 eair as it passes to the machine, and some of the lubricant is deposited in the cook to render the latter easy and free in operation. I One of'tlie marked featiu'es of my device is go the economylsecured in the quantity of lubricant utilized for the pro er oilin oft-machincry, and this is due to t. e fact t lat the cartridge is dissolved only when themachine is i in serviceand the air is circulating around Specification of Letters Patent.

said cartridge. Theestimated cost 'of lubrication, com ared to the present liquid method of lu rication, is about ten per cent.

A cartridge or char e ,aboutone' inch in dimated, last from six to twelve hours, according to the dryness of the air. I

My improved device also embodies means a cartridge may be easily'and quickly laced in position, andalso includes adjustab e devices ada ted to vary'the area of the cartridge expose to the disintegrating influences of the air-current, thus making provision for regulating the supply of the luiricantto the workingparts. v "With these ends in view the invention consists of a lubricator' embodying novel fea-v tiires of construction and arrangement of parts, which will -be hereinafter fully. de- L scribed, and the actual scope of the invention will he defined by the claims. 7 5 Reference is to be had to theaccompanyeing drawings forming a part of this sp'ecification, in whic similar characters of reference indicate-correspondingparts in both thefigures. I p 80 Figure 1 is a vertical longitudinal sectional elevation through the lubricator embodying my'invention andshoWing a solid cartridge. or charge of lubricant in position therein, and Fig. '2isa vertical transverse section in the plane of the dotted line 2 2 of Fig. 1.

In carryingmyinvention into practice, I providea casin which is constructed with a chamber for t e rece tion of a solidified charge or cartridge of ubricant, said casing 9o havin means for the circulation of a motive fluid through the same and adapted" to house the several working parts for holding the charge or cartridge in an exposed osition. I

,J-n the preferred embodiment o the inven- '5 tion shown by the drawingsthe cartridge container is represented in. the form of an elongated shell 5, and to this shell is united a casing 6 by means of the screw-,threaded- 5' joint 7, said casing 6 being provided with the '10:: female-threaded sockets 8 v9, which are-adapted for the attachment of pipes (not'shown) suitable for conveying the motive fluid to.

;an d from the lubric'ator, aswill be readily understood. The casing 6 is rovided with 8. 39 5 circulating-chamber 10, whic may take the form. shown more clearly by Fig. 2; and through this casing extends the cartridge-r containingshell 5. The shell is shown by the drawings. in the form of an elongated cylinder; but the articular shape is not material. The length of the shell greatly exceeds the 5 diameter of the casing, and said shell has its end portions extende or projected from pposite sides of the casing, thereby exposing the end portions'of the shell to convenient aec'ess and making it ossihle to adjust the reg 1o ulating deviceswit out disturbing the connection of the lubricat-or to the circulatingpipes. The shell 5, which extends through the circulating-chamber IQ of the casing, is provided with a series of radial slots or open- I 5 mgs 11, thesame terminating within the limits of the ch amber and adapted to expose the cartridge to the disintegrating influence of the current of motive fluid, the latter circulating through the chem-her l0 and having an access to a large area of the cartridge, owing to the presence of the slots or openings 11 in the csrtridge-conteining shell.

As hereinbefore described, the cartridge is mzute'of oil and grease or any si iitablelubri- 2 5 eating matter, which is treated to-reduce-it to a solid condition, such-treatment; beinge'f- 'fecte'd chemically inorder to render the-cartridge soluble when attacked by moisture. This certrideis i-n'd-icate'd lit-12 and is fitted o-or containe Within the slot-ted part of the shell 5, thus eXposi-n the cartridge to the circulating motive flan traversing the ehaniher '10 of the-hrhricstor.

The shell-5 is adapted toeontains'djizstahle 5 means stl'ording analmtment for one of the solidified cartridges, and this adjustable means is embodied in the form of a head or disk whiehdsiprovidcd with a stem 14,

A tight joint is secured between the cap and sleeve and the casing by interposing a gasket or packing 2-1 between the end edgeoi the casing and the interior face of the cap. Within this rapped sleeve, which is thus reniovahly fitted in the end portion of the shell opposite to the regulating device, is housed or. wntainr-wl a inovable or yieldahle plunger 2:3. the latter lacing adapted to engage with one end portion of the cartridge 12 and coripem-ting with the adjustable head 13 in a manner to eon'iine and hold the cartridge against displacement within the shell. 'lhis plunger 25 is preferably chambered in order that it may receive one end portion of a pressure-s )ring 26, the latter being contained in the sleeve 20 end havin its other end seated against the cap 21-. he spring is norn'ially ell eel ve in forcing the plunger into engagement with the certrid re, and this plunger and the spring are removsole and insertihle with the meme 20.
